My invention relates to metallic carroofs, and :consists in the novel and useful combinations and organizations of parts herein described and. then pointed out in the appended claims.

One of the objects of the present invention is to provide a new and improved arrangement of parts whereby the distance between the roof-panels and overhanging carlineflanges will be uniform and predetermined by the depth of the carline-web in order that the inturnecl ends of the carline-caps may be made uniform and provide. a stormtight joint.

Other objects are to provide a sectional ridge-cover whose parts shall lie between and flush with the adjacent carline-caps; to provide a ridge-cap covering and interlocking with the adjacent ends of an opposite pair of carline-caps and an opposite air of ridge-cover sections; and to provide that the bolts holding the ridge-caps shall connect metallic parts so as to avoid the looseness that would be consequent on the interconnection of wooden and metal parts.

Other objects will be apparent from the disclosure which made in connection with the accompanying; drawings showing practical embodiments of the various parts of my inventiomand in which Figure 1 is a top plan View of part of a car roof embodying the several features of my present invention with various parts cut away to afford better illustration; Fig. 2 is a cross-sectional view of one side of the car-roof taken online 2 2 of Fig. 1; Fig. 3 is. a detail sectional view showing the parts at the crossing of a purlin and carline taken on the line 3-3 of Fig. 2; Fig. 4 is a detail end-view taken at the end of one of the carlines at the eaves with the downturned end of the carline-cap broken away; Fig. 5 is a cross-sectional view on the line 5-5 of Fig. 1 showingone of the carlines and its end-brace in position with reference to a side-plate; Fig.6 is a perspective plan view of one of the end-braces or brackets of the cal-lines; Fig. 7 is a cross-sectional view at thejunction of ridge-pole and one of the carlines taken on the line 7--7 of Fig. 4; Fig. 8 is a longitudinal cross-sectional view of the same parts parts in horizontal section being taken on the line 9-9 of Fig. 25; Fig. 10 is a perspective view of one of the carline-caps, and Fig. 11 is a similar view of one of the sections of the ridge-cover.

In the drawings the reference numeral 1% designates the ridge-pole, 18 the side plates, bolted to the side-plates at intervals along their length, and 15 the longitudinal wooden purlins.

Extending transversely of the car at suitable intervals are the metal carlines which in the present invention are double troughshape incross-sectionextending from side to side of the car and resting upon the sideplates and ridge-pole into which they are stepped as shown in comprises a lower horizontal flange16, lower vertical webs 17, intermediate horizontal flanges 18, upper vertical webs 19, and upper lateral flanges 20, the horizontal flanges 16 being extended beyond the side-webs and side-plates of the car and bent down to form seats for the side-plates as at 21. The carlines are stepped into the side-plates, purlins and ridge-pole a distance slightly less than the depth of the vertical webs 17 so that the intermediate horizontal flanges 18 rest on. these parts, and the webs 17 and flanges 18 form angular seats in the carlines in which these parts rest, the purlins, ridge-pole and side-plates being cut-out or recessed somewhat in excess of the length of the webs 17 in order to provide a clearance between them and the flanges 16 and that the carlineseats shall rest thereon. The carlines are connected to the ridge-pole, .purlins and side-plates by bolts or other suitable connecting devices as clearly shown at 22 in Figs. 1 and 2, so that the carlines carry the purlins and the superposed roof-sheets. The flanges 20 of the carlines are substantially straight from end to end so that the width of the carlines is approximately uniform throughout their length, and the webs 17 and 19 are of uniform height, respecthe talten on the line S-8 of Fig. 7; Fig. .2) 1s a view of the same 14: the carline-brackets or braces Fig. 2. Each carline 1 The roof sheets or panels 23 extend from the ridge pole outward to the eaves resting upon the purlins,'and each sheet or panel is substantially rectangular in shape and is provided with upturned side-flanges 24,'an upturned inner or ridge-flange 25, nd a downturned outerflange or end 26 adapted to extend down upon and be fastened to the outer face of the side-plates. The side-flanges 24. of the panels lie under the flanges 20 of the carlines, with suflicient clearance between the parts 19, 20 and 24. to allow play to the latter along their length.

The carline-caps are of metal and are of inverted trough-shape in cross-section consisting of an upper horizontal portion 27 of suflicient width to overlap the carlineflanges 20 and adjacent flanges 24 of a pair of roof-panels or plates, downturnedlsides 28, and inwardly and upwardly extending side-flanges 29; and they extend, from the ridge-pole where each is provided withan upturned cross-flange 30 outwardly to the eaves where each is provided with a downturned outer end 31 overlying the downturned portions 21 and 26 of the carlines and roof-panels, the bolts 22 passing through the downturned portions 21 and 31 and the side-plates. Afterthe roof-plates are assembled upon their supporting purlins on each side of the carlines, the carline-caps are slipped into place, each along the length of the associated carline from the eaves to theridge-pole and covering the flanges 24: of the adjacent panels beginning at the outer end, and when each cap is in position its downturned sides cover the lateral flanges 20 of its carline and v overlapth'e up turned flanges 24: of the associated panels, leaving a clearance so that the latter flanges are free to move or playunder strains or twisting actions of the car. The webs 17 and 19 are of uniform height respectively along the length of the carlines, and as the recesses in the purlins, side-plates and ridgepo-le are of greater depth than the webs 17 and as the carline-seats formed by the flanges 18 rest on these parts thedistance between these parts and the flanges 20 is uniform. so that the flanges 29 of the carlinecaps, being made of such height as to flll the space between and press against the panels and the underside of the flanges 20, hold the panels in place and provide a water-- tight joint. By this organization the roofplates are interlocked with the carlines in such manner as to retain them in position but permit them to have play or movementtively.

under any strains to which the car may be "subjected, the side flanges of the panels have room for play between the carlines and the downturned sides of the caps. The carlines being stepped into the purlins brace each purlin from the adjacent ones instead of merelyfrom the end-frame of the car, .and

cap-plate which provide a the purlins also brace each carline 'from the adjacent ones; .and the carlines being also stepped into the ridge-pole and side-plates brace these parts. The carlines are connected to the side-plates the metallic end-braces or brackets 13 which are V-shape in general contour the apex being bolted or riveted to the flange 16 of the carline and the ends being similarly secured to the side-plate on each side of the carline. The arms of the vbrace are provided with upturned flanges l4 intermediate the side plate and webs 17 of thecarlines to straddle the carlines being beveledtolie flush, there with, and .to' brace the carlines and side plates. I

I "also provide a sectional metallic ridgee cover, each section being located between a pair of adjacent carline-caps at the ridge or center and extending longitudinally of the car and over the upturned [inner or wings restt- "Each section'of the ridge-cover consists of a trough shaped structure comprising a top or upper portion32 and down-, turned sides 33 having lateral flanges 34 rest'upon the upperv adapted to overlie and faces of a pair of opposite plates or panels 23wit-h the upper flanges 25 thereof in the trough provided by the sides and top. The

top and sides'are provided respecti'vely'with upwardly and flanges 35 and 36, the latter lying flush against the sides 28 of adjacent associated panel-caps to protect the opening or space between these parts, and theformer lying under and interlocking with a malleable is bolted to an associated an opposite pair of caradjacent opposite sections carline and holds line-caps and the of the ridge-cover in place and also pro-;

vides a base for a running-board saddle or support. Each cap is provided with a raised central portion 37 and four lateral arms 38 and 39 arranged in opposite pairs and trough-shape in cross-section.- The arms 3'8 the top 37 to provide shoulders 10 The arms 39 are ofl'set as at 41 so as to be below the plane of the top of the arms 38 and to over the inner end of a carline-cap, the flanges 30 of which rests under the top 37 and adjacent the shoulders 4. .0, and each arm 39 fits over the 'endof one of the sections of the ridge-cover, the flange 35 of which rests behind a shoulder 42. In assembling the parts thecarline-caps and the ridge-cover sections are. placed in position with their respective flanges 30'and are oppositely inclined to fit the pitch of the roof, and are below'the plane of shoulder 42.. Each arm 38 fits,

ridge-flanges 25 of an opposite pair of roof plates upon which its opposite flanges or laterally bent wings or p 35 arranged in adjacent position at the crossing of each carline with the ridge-pole,

and the ridge-caps are then: placed over these flanges and bolted in place by the bolts 43 which pass through the lower horizontal flanges 16 of the carlines. By this arrangement the malleable ridge-caps are secured to the metal carlines instead of to the wooden ridge-pole as heretofore, so that looseness due to differences in shrinkage and wear of the wood and metal is obviated, and the adjacent sections of the ridge-cover and the inner ends of opposite carline-caps are held in place by a single connecting cap.:

The saddles 44 of the running-boards 45 are stepped over the ridge-caps sons to be held against displacement sidewise of the car and the through bolts 43 pass up through theisaddles which are cut-away to receive the intermediate nuts which clamp the caps in place, the grip-nuts 47 holding the saddles on the caps.
